To all'whom it may 00nce7n:

Be it known that I, JOHN H. DEPPELER, citizen ofthe United States, andresident of Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Apparatus for Facing theEnds of Pipes, &c., of which the following is specification.

This invention relates toan apparatus for facing the" ends of pipes,etc., and'the main object o'fthe' invention is to provide an um I thistype especially parts, by meansiof'which the end of the work to bef'aced.may be brought into the desired plane at a predetermined angle to thelongitudinal axis of the work.

In welding pipes, bars, rails, girders, and other: similar parts it isnecessary to face tlieisurfaces to be united to true planes and thenbring them into exact parallelism. This is accomplished by means offacing tools or cutters, usually driven by hand, by means of" which thefacing tool may be turned to dress; the end of the pipe or other part.

The present invention relates to such a facing apparatus; and theprincipal feature 'offth'ej invention is the provision of a clampattachable directly to the pipe or other part and carrying a facing'toolmounted on the clamp, in such a manner that it may be turned in-aplane'at the exact angle to which bring the end of the work,-

it isdesired to and also fed in the direction of the longitudinal axisof the work.

Other features of the invention not hereinbefore referredto will behereinafter described and claimed and are illustrated in theaccompanying drawings, in which- Figure l is an end view, partly brokenaway, of a facing apparatus embodying the invention; Fig. 2 is asectional side elevation of the same; Fig. 3 is a plan view of the samein a slightly modified form, and Fig. 4: is a detail illustrating inelevation a facing tool suitable for use in the apparatus.

Similar characters designate like parts in all the figures of thedrawings.

In the particular embodiment of the invention illustrated in thedrawings I have shown the facing apparatus as embodying a suitable clampfor engaging the work, this clamp being illustrated as a pipe-clamp p.This pipe-clamp comprises in the present case a main fixed element orbody portion, 2, having suitable roughened gripping surfaces, portion isconnected a yoke, such as: 4, adapted to carry the movable element ofthe clamp. porting portions of the fixed element 2 constitute the fixedjaw of this'clamp, the movable j aw of which may be constructedsubstantially as shown at'5, it being of the typeordinarily employed inpipe-clamps and be-' this instance at one end ofling mounted in athreadedrod, 6, which passes through a threaded nut,7, of the yoke 4 andis adapted to be adjusted up and down to release or grip the pipe 79 orother part to be held.-

The threaded. rod 6 may be turned in the usual manner, as bymeans of abar, 8." Theseparts just described aresuflicient'for the purpose ofinclosing and engaging one endof the pipe or other work to be held andlocating it in a predetermined relation. to the clamp and the otherparts of the facing apparatus. r

In the construction illustrated the fixed. element or aw of thepipe-clamp is ofconsider'able length in order that it may presentrelatively'long. gripping surfaces 3fto'v of the workand alsothefacingengage the periphery to furnish a suitable support for toolproper. This facing tool-is intended to be mounted crosswise of the workto bring its axis of operation with parts'of various diameters. In ordertoprovide for this adjustment it is mounted in a bearing carried by acrossslide, 9, adjustable up and down transversely to the axis of thepipe 9. This cross-slide has relatively long slots, 10, through whichpass pins or bolts, 11, which in turn carry on their outer ends clampnuts, 12, bymeans of which the slide may be securely clamped to the bodyportion 2 in any desired crosswise position. This slide has aninternally bored sleeve, proper for the facing tool. This bearing isindicated at 14: and is externally threaded to fit into and cooperatewith the internal threads of the sleeve 13. It is intended to receive asuitable spindle, 15 to which is secured at the inner end of the spindlea facing tool, such for example as the cutter shown at PatentedJan, 11,rare.-

3, and to this main body The gripping surfaces and the supin a bearingat one side of the central crosswise plane of the clamp and is also inthe preferred construction adjustable- 13, into which is threaded thebearing 7 movement to the tool.

0. The parts just described are sutlicient to permit the tool 0 to beturned about its axis by the SQlIlCllG and at the same tune fed forwardtoward the work to be dressed means will be employed for turning thespin dle and this bearing. Here a hand-wheel is shown at 16 as splinedon the spindle 15 and as having means for coupling it to the sleeveThe'coupling means illustrated may be the ordinary clutch parts, that isto say, teeth, such as 17, on one of these parts adapt ed to be receivedin corresponding notches, 18, on the other. When the sleeve 13 and thehand-wheel 16 are coupled together in this manner the sleeve, as well asthe spindle 15, will of course be rotated wnen the handwheel is turned,and in addition the sleeve will be fed toward the work. By thisactionwthe tool will not only be rotated but will also be advanced thedesired extent at each rotation.

In Fig. 2 the construction shown is one in which the hand-wheel and thesleeve 13 are constantly coupled so that the sleeve will always beturned to advance the tool at each rotation of the hand-wheel.

In Fig. 3, however, which illustrates a modification of theconstruction, the spindle is extended suiiiciently to permit thehandwheel to slide on the spindle a distance sutficient to enable it tobe coupled toor uncoupled flOlIl the sleeve 13, as desired, so that saidsleeve may either be turned with the hand-wheel at each rotationthereof, or only coupled thereto at intervals and turned as often as itmay be desired to impart feed Owing to the fact that the position ebearing for the facing tool is adj t. this tool can be shifted so thatits center coincides with the center of the surface to be faced or is inany other suitable relation thereto.
